At the core of the internet lies DNS or the domain-name system. It employs a distributed database (DDB) to map domain names and IP addresses across the web. DNS
makes it convenient to access the internet, so that instead of memorizing IP numbers, people can use words to make domain-names.
The device supports the following two functions through the domain name configuration service:
 DNS Server: the device can function as a local DNS Server.
 DNS relay: as a DNS agent, the device can transfer DNS request and response
messages between the DNS client and server, while and executing domain
name analysis in place of the DNS Client.
To begin setting up the DNS client, find the navigation panel, select Network>>DNS
to enter into the “DNS” window and manually set the DNS information. If the DNS
information is empty, it can be found via dialup. Generally, users will only need to set
the dialup DNS settings if they have static routes on the gateway.

DDNS (Dynamic Domain Name Server) automatically adds DNS entries to a server
in real time. DDNS automatically logs IP addresses and host-names to its database
when hosts connect to the network. When hostnames have been recorded, they may
be used in the place of IP addresses. DDNS will be particularly useful in an IPv6 environment.

Static routes are created manually and have many different uses. After the static
route is set, packets will be transferred to appointed routes. Engineers can create
simpler networks by using static routes in place of RIP or OSPF, and ensure greater
network reliability. The proper setting and use of static routing can also improve the
performance of a network and guarantee bandwidth for important network applications. The device supports up to 20 static route entries.

In the service section, this manual covers nine configurations, including DHCP service, DNS relay, VRRP, Device Manager, DTU, Modbus to SMS, SMS alarm rules,
and Mbsms variable template.
3.4.1 DHCP Service
DHCP (Dynamic Host Configuration Protocol) is a network protocol for LAN utilizing
UDP and TCP. DHCP automatically distributes IP addresses for either a local network or network service provider, and can aid network administrators in managing all
the computers on a network. A DHCP server refers to a computer managing DHCP
standard in a network. It distributes IP addresses once the work station logs on and
ensures that no duplicate IP addresses are assigned. DHCP Server dramatically simplifies network management tasks, and is a necessity in today's network.
To enable the DHCP server, find the navigation panel, select Services >> DHCP

3.4.3 VRRP: Virtual Router Redundancy Protocol
VRRP is a protocol for allowing automatic failover and redundancy in routers. It creates a “virtual router,” meaning multiple physical routers can be assigned to one gateway or one host. The main gateway controls the IP of the virtual gateway and routes
packets to virtual IP addresses. If the main gateway drops, a dynamic failover process elects a new gateway. The IP address of the virtual gateway can be set as the
default gateway for hosts, because it is the first hop. The benefit of using VRRP is
serviceability. The network administrator can avoid the configuration of dynamic routing or routing discovery protocol on each host.
To enable VRRP, go to the navigation panel, select Services >> VRRP, then enter

3.4.5 Modbus to SMS
EKI-1331 inquires the variables status of the PLC every ten seconds and saves them
into RAM. These variables will be the SMS response sent after a query. After receiving a control SMS, EKI-1331 sends the control command to the PLC and waits for a
response. The response is sent from the PLC and then EKI-1331 sends the response
to the user.
To enable SMS, find the navigation panel, select Services >> Modbus to SMS to
enter into the “Modbus to SMS” page. After you add your PLC here, the daemon of
EKI-1331 periodically queries the PLC variables and cache to memory.
Follow the five steps below to configure the PLC parameters:
1. Click ‘Enable’ in ‘Service>>Modbus to SMS’
2. Unfold configuration item of “PLC List” and click the PLC to be used, and configure one by one. 8 PLCs could be added on this page.
3. Configure the specific parameters of PLC, each PLC can be added to 32 variables.
1). Set the modbus type. Only RTU is available on this model.
2). Configure the slave address of each PLC, namely the ‘Modbus ID.’ It may be
assigned a value from 1 to 247.
3). Configure name of the PLC, using a maximal length of 16 bytes. It is important to name PLCs to avoid confusion in a large scale operation.
4). Enter the register address, or modbus variable address, in the first column.
0xxxxx is for discrete inputs. 1xxxxx is for a coil. 3xxxxx is for the incoming
register, and 4xxxxx indicates a holding register.
5). The second column is the variable type, supporting BIT, WORD, DWORD,
FLOAT, INT16, INT32 and INT64.
6). In the third column are the units of variable with maximum length of 8 bytes.
This value will appear in SMS, and you can leave this field empty. The unit of
BIT variables should be configured according to HH/LL format, HH represents the corresponding unit of “1,” LL represents the corresponding unit of
“0.” The units of other types of variables will appear directly in SMS.
7). Enter the register name in the fourth column. This is simply the name of the
variable with a maximum length of eight bytes. Users can define names for
EKI-1331 User Manual

Select a variable name in the second column, and the corresponding variable of
the PLC will appear above it. The technician will compare values to this variable.
Compare the variable to a value by selecting an operator in the third column.
The available options are: NONE, >, >=, <, <=, = and !=.
Define the first value in the fourth column. This value will be compared to the
main variable. For example, temperature >= 200 means that when the temperature is greater than or equal to 200, an alarm will be sent.
Define the relationship between the first expression and the second expression
in the fifth column by selecting OR, AND or XOR.
Select a second operator in the sixth column. The options that can be selected
are: NONE, >, >=, <, <=, = and !=.
Define a second value in the seventh column.
In the eighth column, the user must define a dead zone, which acts as a buffer.
After the alarm is trigger, it will not be sent until the variable exceeds the dead
zone value. It is only effective for numerical, non bit-wise values. Set the value
to zero to eliminate the dead zone.
In the ninth column titled “ACTION?,” users may select “YES” to enable userdefined alarm message, user need define the alarm message on “Context” in
the eleventh column. Otherwise, the default alarm message will be sent. The
maximum length for a short message is 140 bytes.
The mobile phone number of a recipient is input in the tenth column.
A user-defined alarm message may be set in the eleventh column. When triggered, this message will be sent in the form of an SMS.
The alarm SMS are divided into two types:
 If the selection for “ACTION?” in the ninth column is NO, the system will send
the automatically generated defaulted alarm short message. The message will
be defined by the variable, for example: “Alarm plc2 OUPUT=on,” or “Alarm plc
AB_VOLT=238V.”
 If the selection of “ACTION?” is YES, the system will send a user-defined alarm.
Below is an example of an alarm rule:
Caution! The first rule states that when the OUTPUT1 of plc2 changes from 1 to 0
or from 0 to 1, trigger the alarm and send the alarm SMS to all users in
the “alarm user list.”
The second rule states that when the variable value of AB_VOLT in plc2
is less than or equal to 20 or greater than or equal to 230, trigger the
alarm and send the user-define SMS to the user ‘13810556243.’ In other
words, when AB_VOLT is between 20 and 230, plc2 is in normal operating conditions.
